288 A. AluOck— of Pleuronectidns/wju tlie Bay of Bengal. [No. 3, 



I have named this species after the distinguished officer in charge 

 of the Marine Survey of India, Commander Alfred Cai-penter, R. N., D. 

 S. 0., the pioneer of scientific hydrography in India. 



15. Ctnoglossus macrolepidotus, Sleeker. 



Guntlior, Cat. iv, 496 ; Day, Pishes of India, p. 434, pi. xovi, fig. 3. 

 Met with usually on soft and muddy bottoms, in 7 to 10 fathoms, 

 oif the central part of the delta, where it is exceedingly common, and 

 grows to a length of one foot. 



16. Ctnoglossus oligolepis, Bleeker. 



Giinther, Cat. iv, 496 ; Day, Fislios of India, p. 433, pi. xcv, fig. 4. 

 This species was always found with 0. macrolepidotus, chiefly on 

 soft bottoms, in 7 to 10 fathoms, where it reaches a length of nearly fif- 

 teen inches. 



17. Ctnoglossus quadeilineatus, Bleeker. 



Giiutlier, Cat. iv, 497 ; Day, Fiahea of India, p. 435. 



Met with by the ' Investigator' only on bottoms of hard sand, in 6 

 to 10 fathoms, in the southerly part of the region, 16 to 30 miles S. W. 

 of Pari. 



18. Ctnoglossus lida, Bleeker. 



Giinther, Cat. iv, 498 ; Day, Fiahea of India, p. 436, pi. xcvii, fig. 3. 

 A number of specimens were taken oa one occasion, with a large 

 number of 0. quadrilineatus. 



19. CTNOaLOSSUS INTEEMEDIUS, n. sp. ? 

 D. 106. A, 85. L. 1. 100-103. T. 4. C. 10. 



This is a form which has characters similar to those of both 0. lida 

 and 0. bengalensis. Only one specimen was taken at the same time with 

 0. quadrilineatus, to which also it has a strong superficial resemblance, 

 and with 0. lida. In appearance it is hardly to be distinguished from 

 the latter, but the ventral fin is united with the anal, the scales are more 

 numerous and less ctenoid, and the head is proportionately longer. In 

 appearance it would not be confounded with the specimens of 0. bengal- 

 ensis in the Indian Museum, though the description is not remark- 

 ably different. In describing it from a single specimen it is not yet 

 intended to establish a new sjDecies. 



Symmetrical semicircular snout, abruptly pointed tail. 



On the left side . two lateral lines separated by 14 rows of scales ;
